Serial No. 571,096.

This invention relates to improvements in radiators, and has for itsobject to provide a radiator in which the headers are cut' back so thatsections of the radiator can be joined together without there being anyappreciable amount of space between the sections forming the completeradiator structure.

It is an object of this invention to provide a radiator sectionconsisting of heads united by pipes, across which fins are arranged forheatradiation and distribution. The parts of the heads are formed ofsheet material such as sheet steel, andare welded together to form theheads, to which the pipes are also welded.

It is also an object ofthis invention to rovide radiator sections inwhich the heads have cut-back portions, into whichconnecting nipples maybe inserted for connecting 20. thessections of the radiator to form acomplete radiator of one continuous structure, with no spacetherebetween.

It is a further object to provide guardmeans on the ends of the sharpheat radiating steel plates so that the radiators can be lifted withoutinjury to the operator, as these radiators are of considerable weightand without these guards it would be dangerous to handle them.

It is a further object to provide a novel header construction of lesserwidth than the general width of the radiator and integrally formed withthe heating pipes, as well as rigidly connected to adjacent sections ofthe 5 radiator.

These and other advantages will appear from the following descriptiontaken in connection with the drawings.

Referring to the drawings:

Figure 1 is a side elevation showing two radiator sections united toform a single radiator unit. v

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a view showing the upper ends of two radiator sections, witha part of one radiator section in section to show the nippleconstruction.

Figure 4 is a view taken on the line 4-4:

of Figure 3.

Each heater section is composed of an upper header, a lower header,connecting pipes an arclrshaped passageway, having a flatbottom, thesides and top of which are formed by the wrapped plate -1, while thebottom or flat part is formed of the plate 2. When the header is used atthe lower end of the radiator section or radiator unit theiparts arereversed from what they are at the upper end thereof. t The wrappedplate is shorterthan the horizontal or tube-supporting plateil. the sideof the wrapped plate adjacent the plate 2 is of the same length astheplate 2. At each end of the header is an 'end member 3 having a lateralandoutwardly inclined pro-V jection 4. This end member with theprojection i completely ,incloses one end of the header and two of theseend members and projections inclose both ends of the headen Each endmember is attached to the plates, both 1 and 2, by means of welds 5 sothat these parts, when finished, areintegral one with the other so theheader is formed of one continuous piece of metal.

. lVhen the end members have been welded to the plates there is leftacut-back portion the nipple is threaded into a threaded .open-.

ing or hole 7 in the end member 3. Two of these nipples are used forbinding two sec- L. 4 1, v I 110113 of tne radiator, as shown in higuie1.

nipple in the cut-back parts and rotate the nipple so that the threadson the ends of the nipple will engage the threads in the holes in theend members. And in order that the nipple may operate to connect the twoadjacent sections the threads on the ends of the nipple are oppositelythreaded, and the threads in the end members are made to correspond withthe threads on the nipple.

The foregoing is a description of the construction of the head and themanner in which two headers may be united so that radiator sections maybe united.

In order to form a complete radiator section two headers are united bymeans of tubes 9. Each end of each tube projects through a tube headerplate and is welded thereto, as indicated by the numeral 10. These tubesmay be of any convenient shape. As shown in Figure 4 they are oval. Supported by these tubes and in parallel relationship to the header tubeplates are steel fins 11 formed from thin steel plates. T hese fins haveholes therein to receive tubes.

At the ends of certain of the plates and attached to the sides thereofare reenforcing plates 12, which are welded or otherwise permanentlyattached to the sides of the fins. The purpose of these plates is toform a support for a cover plate 13 fitting over the ends of theradiator fins. The cover plate has lateral flanges 14, which areattached to the reenforcing plates and to the fins bymeans of bolts 15.There may be any desired number of these bolts and reenforcing plates.

The radiator isheated by means of some heating fluid, which is admittedto the radiator by means of a pipe 16 and discharged therefrom by meansof a pipe 17. The heating fiuid goes into the radiator at one end andpasses down through the pipes into the header at the other end.

This radiator is so constructed that either end may be used as the topor bottom part of the radiator, both headers being identical. A radiatorconstructed in the manner herein set out is strong, durable and is welladapted for use in manufacturing plants, power houses and the like wherea large quantity of radiating surface is needed, "and where, in order tosupply this surface, a rigid structure must be provided.

This rigid structure is alforded by means of applicants headerstructure, composed essentially of a one-piece sheet of hollow metalsuch as is formed by'bending and properly shaping plates of steel andwelding the Two of these headers united by pipes form a rigid, strongand durable section unit, any number of which may be connected in themanner shown in Figures 1 and 3. Stress is particularly laid on the factthat all parts are welded. There are no bolts or rivets with theexception of bolts for holding the cover plate in position. This plateis merely to protect the hands of the workman when moving or installingthe units.
